I started by looking at the selling prices of similar cars. The closest match is the 2013 BMW 730 V6 3.0L Twin Power Turbo with 60000 km, sold for 70000 SAR in January 2024. Given that the car in question is a 2012 model with lower mileage (44500 km) and in good condition, it should be valued slightly lower due to being a year older. The 2012 BMW 730 I6 3.0L Twin Power Turbo with 98000 km sold for 59000 SAR in September 2023, but it had higher mileage and was in average condition. The 2012 BMW 730 I6 3.0L with 159000 km sold for 54000 SAR in April 2024, but it had much higher mileage and was in average condition. Considering these factors, I adjusted the price upwards from the 59000 SAR benchmark for the lower mileage and good condition, but slightly lower than the 70000 SAR for being a year older.
